Web-based and transparent “line of
sight” between data and conclusions
Usefulness for “the Public”
Highly understandable language with
graphics that help "tell the story"
- of the difference between climate
variability and change.
- how we can tell the difference
between "normal" variability and longterm trends.
- examples of the kinds of observed
changes and adaptations
-
8 Regions addressed
